I'm going tomorrow to look at 2 MH's one a gasser one a pusher, the pusher is a 1997 with a 275 cat.. 100k miles.. how do I check for electrolysis in the cat or is this a non issue? thanks!
Cavitation is only an issue with sleeved cylinder engines. Engines like the Cummins B series don't have sleeves so will never have this problem. IF you have a sleeved eng then you need to keep up on coolant chemistry.
